保山市道街区的主要水稻品种为南特占、赤脚矮、铁克矮等经过多年种植后不但丰产性差,抗逆性弱,而且也不注意栽培技术,每季水稻平均单产为600～700斤,全年早晚稻两季平均单产为400～500斤,人均粮只有600斤。为了充分利用本地自然优势,极积发展各种经济作物面积,又不减少粮食产量,我们自1984年以来,积极推广“两杂”。杂交玉米:1984年推广1120亩,1985年推广6743.75亩;杂交水稻:1984年推广21亩1985年推广375亩,实行早玉米与中稻连作,即解决本地3～4月用水困难、粮经争水的矛盾,还能改善土壤的
The main rice varieties in Baoshan Street area are Nantezhan, bare feet and dwarf shorts. After years of planting, Tieke dwarf not only has poor high yield, weak resistance but also does not pay attention to cultivation techniques. The average yield of rice per season is 600 ~ 700 kg The annual average yield of rice in the two seasons of the year is 400 ~ 500 kg and the per capita grain is only 600 kg. In order to make full use of the natural advantages of our region and to develop a great variety of cash crops without reducing the output of grain, we have been actively promoting “two types of problems” since 1984. Hybrid corn: 1120 mu in 1984; 6743.75 mu in 1985; hybrid rice: 21 mu in 1984; 375 mu in 1985; The contradiction, but also to improve the soil
